IMPROVEMENT IN COTTON-PICKERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it 'may concern.: A

Be it lmowntliat I, DANIEL M. MGRAE, of Webbei-ville, in the county ot' Travis and State of Texas, have invented a new and useful Improvement in Cotton-Pickers; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompany-j -into a receptacle behind, all as hereinfter more fully specified.

Figure l is a longitudinal sectional elevation of my improved cotton-picker, taken on the line :c x of Iig. 2.

Figure 2 isa horizontal section through the line y y of lig. 1.

Similar letters of reference indicate corresponding parts.

A is the frame, and

. B the wheels of a truck, ot suitable construction' to be drawn along the row ot' cotton-plants, with one wheel on each side, by horses or other animals.

C represents the saws, which may be of any preferred construction. They are arranged in Va gang, and mounted in the front of the truck-frame, so as to run a short distance above the ground, and so that they' move upward at the front.

The shaft of the saws-is connected by a pinion, D,

and large spur driving-wheeLE, vwith one of the wheels of the truck so as to be set in motion thereby when the truck is moved along.

F represents guards, consisting or" long thin bars attached to the rest G, and running rearward, one between each two saws, to prevent the sticks and other foul matter being carried up witlrthe cotton.

H isthe brushing-drum, arranged ia the case at the rear upper side of the saws, to brush the cotton off the teethot' the saws into the receptacle I below.

This brushing-roller is designed to be rotated considerably faster than the saws, to insure the taking utf of the fiber, and it is operated, in this instance, by a belt, K, working over a large. pulley, L, on the saw shaft.'` It may, however, be operated in any other approved-way.

M represents plow-shaped gatherers, attached to the frame at the front,l to run under the laterally hanging branches and gather them up to the range of the saws, to be acted on thereby.

It is believed that thesel saws will eiectually strip the cotton from the branches ot' the plants without.

materially injuring them, in a very rapid and economdrum H, as shown and described.
